Exam 21: Cardiovascular System Function, Assessment, and Therapeutic Measures

A patient has sustained damage to the sinoatrial node.Which heart rates indicate that the patient's atrioventricular node has taken over as the pacemaker for the heart?

The nurse determines that a patient's pulmonary artery wedge pressure is normal.What range of values did the nurse use to make this decision?

The nurse is reinforcing teaching provided to a patient about the role high-density lipoproteins (HDLs)play in cardiac disease.Which patient statement indicates correct understanding of the teaching?

While collecting data a patient expectorates pink frothy sputum.Which health problem should the nurse consider is occurring in this patient?

The nurse is helping a patient understand why the heart beat can change in speed.When doing so,what should the nurse explain as being the pacemaker of the heart?

The nurse is reviewing the role of atrial natriuretic peptide (ANP)in blood pressure regulation for a patient with hypertension.What should the nurse include in this discussion? (Select all that apply.)

The nurse notes that a patient being prepared for a cardiac computed tomography (CT)scan has mild renal insufficiency.What should the nurse expect to be ordered before and after the procedure for this patient? (Select all that apply.)

The nurse suspects that a patient's heart rate is being affected by parasympathetic influence.What should the nurse recall as the effect the parasympathetic nervous system has on the heart?

The nurse is measuring a patient's central venous pressure (CVP).Which patient factors is reflected by this pressure reading?

A patient with orthostatic hypotension asks why the health problem is occurring.What should the nurse include when explaining the causes of orthostatic hypotension to the patient? (Select all that apply.)

The nurse is caring for a patient who is having an exercise treadmill test.What interventions would be appropriate for the test? (Select all that apply.)

The nurse notes that a patient's lower legs are brown and the feet are blue when they are in the dependent position.For which health problem should the nurse collect additional data?

A patient asks the nurse to explain what high levels of low-density lipoproteins (LDLs)means.What response by the nurse would be appropriate?

The nurse is documenting information collected about a patient's pulses.How should the nurse document that a peripheral pulse was normal?

The nurse is using a stethoscope to listen to a patient's heart sounds.The nurse recognizes that the "dupp" of the characteristic "lubb-dupp" heart sound indicates what part of the cardiac cycle?

A patient being treated for a severe blood loss has a blood pressure of 90/56 mm Hg and urine output of 10 mL over the last hour.Which physiological mechanism should the nurse recall is occurring in this patient?

The nurse instructs a patient on beverages to avoid when taking the prescribed medication warfarin (Coumadin).Which beverage should the patient state that indicates teaching has been effective?

The nurse is planning to auscultate a patient's apical pulse.How long should the nurse listen to the patient's heart?

The nurse is caring for a patient with peripheral vascular disease.Which signs or symptoms should the nurse expect to observe in this patient? (Select all that apply.)

During data collection,the nurse learns that a patient with chronic cardiac problems and diabetes has gained 5 pounds of weight over 3 days and is experiencing fatigue when climbing stairs.Upon inspection,the nurse notes edema of the lower extremities.What health problem do these symptoms suggest that the nurse should report to the physician?
